'The Flash' Season 2 Spoilers: Will Grant Gustin/Barry Allen Lose "Potential Energy?"

The CW network continues with Season 2 of The Flash. After his previous confrontation with Zoom (voiced by Tony Todd), will Barry Allen (Grant Gustin) "lose potential energy" as he goes up against Eobard Thawne aka The Reverse Flash?

In our previous recap, Barry quickly realized he was no match to fight the immortal Vandal Savage (Casper Crump) alone. Needing the help of the Green Arrow (Stephen Amell), the scarlet speedster raced against the clock to protect Hawkgirl (Ciara Renee). Realizing her true destiny, Hawkgirl teamed up with Hawkman and the scarlet speedster to take down their immortal enemy.

In our recent recap, the Weather Wizard (Liam McIntyre) broke both Trickster (Mark Hamill) and Captain Cold (Wentworth Miller) from prison. While Iris was telling her father Joe West (Jesse L. Martin) about his long-lost son, Caitlin Snow (Danielle Panabaker) shared a kiss with Jay Garrick (Teddy Sears). With Captain Cold out of the picture, the Flash raced into the air fighting the Weather Wizard and stopped the Trickster's detonation. As Harrison Wells (Tom Cavanagh) betrayed the others, Wally West (Keiynan Lonsdale) shocked everyone when he arrived at their doorstep.

According to Comic Book Resources, as the metahumans from Earth-2 become an ever-growing threat in the new promo, "Potential Energy." Jay Garrick (Teddy Sears) warns Barry to "...not get distracted by anything you see along the way." The footage also teases the arrival of Killer Frost, Caitlin Snow's evil half.

As we mentioned before, executive producer Todd Helbing dished on the "impossible return" of the scarlet speedster's arch-rival, the Reverse Flash. Eobard Thawne (Matt Letscher) "puts a member of the S.T.A.R. Labs team in unexpected danger," which will force Barry "to make a life-changing decision."

The Flash continues Season 2 on the CW Tuesdays at 8pm on January 19, 2016.
